Enum GraphParam 

pub enum GraphParam {
    Str(String),
    Int(i64),
    Float(f64),
}

A typed value bound to a Cypher query parameter.

Carries the value and its kind so the backend can render each parameter as the correct Cypher literal: strings are quoted and escaped, numbers stay bare. The kind cannot be recovered from a plain string once erased — a LIMIT needs the bare integer 500, while a name needs the quoted literal 'Alice' — so callers state the kind at the bind site rather than letting the backend guess.

FalkorDB’s parameter mechanism textually substitutes CYPHER key=value into the query, so the rendered form must be a valid Cypher literal; this enum is what makes that rendering type-directed instead of a fragile heuristic.

Variants

Str(String)

A string value, rendered as a quoted, escaped Cypher string literal.

Int(i64)

An integer value, rendered bare (e.g. for LIMIT).

Float(f64)

A floating-point value, rendered bare.

Implementations

impl GraphParam

pub fn to_cypher_literal(&self) -> String

Renders the value as a Cypher literal safe to substitute into a query.

GraphParam::Str is wrapped in single quotes with embedded backslashes and single quotes escaped, so a value drawn from user content (an entity name, a memory id) cannot break out of the literal. Numeric variants render to their bare textual form.

Trait Implementations

impl Clone for GraphParam

fn clone(&self) -> GraphParam

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GraphParam

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&str> for GraphParam

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for GraphParam

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for GraphParam

fn eq(&self, other: &GraphParam) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
